The Parisian club has now secured the prestigious trophy on fourteen separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward win in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger opened the scoring early on.
However, Marseille struck two times in the closing moments to take a surprise advantage. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a crucial leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a convincing shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the past thirteen seasons.
